I have used Silver products for several years; but, this is the first year I've added the lozenges. I credit using these lozenges throughout the day (along with taking the Silver Solution) with helping me fight off the nasty respiratory bug going around at work and through my family for the last three months. I won't say there weren't days I didn't feel bad; but, I never got sick or missed a day of work. The lozenges are soothing and have a mild, pleasant taste.
